Product Description
This is a digital file visually explaining the four main strategies used for addition and subtraction during mental math computation. It visually explains the Decomposing Strategy, Branching Strategy (or "Pull Down" Method), Partial Sums Strategy, and Open Number Line Strategy (or "Jump Up" Method). It can be used:

1. during a parent-teacher conference as a handout
2. in small math groups
3. as a resource for an anchor chart
4. blown up and placed on a bulletin board
5. laminated and placed in a math center
6. as a handout for students to place in their math notebooks or journals
7. cut apart and used as flash cards
8. you can include it in a power point presentation as a slide
etc...

These simple documents have come to my rescue many times during parent conferences. They have helped me explain a new approach to computation which is NOT the traditional algorithm to many of my students' parents.

They have also come in handy when explaining mental math to fellow colleagues! It is like a picture and pictures are worth a thousand words!

I hope you find these 2 handouts as useful as I have! ENJOY!

I hope to make one shortly including multiplication and division strategies.
